Homosexuality is a self-defeating sexual act that prevents you from carrying on your genes and prevents you from finding fulfillment because the end result of not finding your complimentary opposite half is either mindless hypersexuality or bed death with no in-between, and any children you steal adopt will wind up with learning disabilities and attention deficits at best or become delinquents or sex fiends at worst.
Transgenderism is a self-defeating fetish/fantasy/delusion that involves intense self-hatred for your immutable biological sex, narcissistic rage at anyone and anything that does not affirm you in your delusions, and self-mutilation and drug abuse.
Both homosexuality and transgenderism are objectively disordered, abnormal, and self-defeating, and most people understand this at a primal, subconscious level. Even gays and troons understand it even if they refuse to admit it.
So to compensate, they go out of their way to convince themselves that being a fag or a troon is awesome, throw huge parties over it, wave ugly flags around. But even when they get the rest of society to celebrate with them and kiss their asses, they're just as miserable and as wretched as ever.
